Patent GB-391629-A (GB)
Title: Improvements in and relating to automatic telephone and like systems
IPC: H04M15/38
Filed: 1932-06-11
Abstract: 391,629. Automatic exchange systems. RUMPF, F., 8, Schwanengasse, Berne, Switzerland. June 11, 1932, No. 16582. Convention date, June 11, 1931. [Class 40 (iv).] A subscriber by dialling a particular single or multi-digit number may obtain connection to apparatus at a trunk operator's position adapted in response to dialling to perforate a card so as to provide the information necessary for setting up the call and to provide a record from which the charge can be made automatically. The apparatus comprises a set of registers for recording the number of the calling subscriber and the exchange and number of the wanted subscriber and a common set of punching magnets RV which are associated with the recording apparatus by mean of a switch SW. After the registers have been set the numbers may be checked back to the calling subscriber phonetically before the card is perforated and an incorrect record may be cancelled. On connection of the calling line to the recording apparatus, line and release relays J, I energize and the first impulse train sets the register EHW. Relays II, III, IV, V energize, and relays II, III relapse in turn at the end of the train and send an impulse to advance the sequence switch FW, so that the second train is directed to the register EZW. Further trains of impulses set the remaining registers in a similar manner. Since the number of digits may vary from six to eight, after the sixth digit is received relays IV, V are dependent only on relay III, so that shortly after the last digit is received these relays fall back and connect up relay L, which transfers the impulse circuit to the sequence switch LW. The recorded numbers are now checked back in the manner described in Specification 386,215, and the subscriber then sends a digit which indicates whether the call is an ordinary or an urgent one. Relays II, III pull up and connect up relay X, which closes a circuit through a pendulum interrupter ST.P. II for stepping the switch SW into association with the recording apparatus, whereupon relays S, P energize. The punching magnet corresponding to the final digit operates over the switch LW, and relay L falls back and causes the card LK to be fed one step. The switch LW now steps under control of an interrupter comprising two relays R, RI and the punching magnets are brought under control of the registers in succession to make corresponding perforations. If the register FEW or the registers FZW, FEW are not set, one or two noughts are stamped before the final digit bv means of circuits over normal contacts w of these registers. The registers restore when the calling subscriber hangs up. Should the punching apparatus be in use, the recorded numbers remain stored until it becomes idle. If desired, the numbers may also be printed on the card to facilitate reading.

Inventor: SPILLANE LEO J
IPC: C07C5/48
Filed: 1956-05-30
Abstract: <PICT:0794157/IV (b)/1> Acetylene and ethylene are produced by the partial combustion of methane and/or ethane at superatmospheric pressure in a combustion zone comprising a convergent section and a divergent section in contiguous relationship, the gases passing thence to a lower pressure zone within such time that substantially no decomposition or polymerization of acetylene occurs, the ratio of the entering pressure to the exit pressure in the combustion zone being between 1.5 : 1 and 10 : 1.  Also preferably the effluent gases are exhausted from the combustion zone to a superatmospheric pressure and are further cooled with water prior to absorption of the acetylene and/or ethylene.  The initial gases may be preheated before combustion.  The combustion chamber takes the form of a nozzle known as a De Laval nozzle.  Referring to Fig. 1, oxygen and hydrocarbon are passed from the storage tanks 1 and 2 respectively into the mixing chamber 9 filled with silicon carbide granules to assist in mixing.  The gases pass thence to a combustion chamber 20 which contains a sparking-plug 19 to initiate combustion and a thermocouple 17 provided with a gauge 18.  The combustion chamber has a convergent section 22, a throat 27 and a divergent section 23.  Generally the velocity of the gases will be about sonic in the throat, in the converging section subsonic, and in the diverging section supersonic. The conditions used are preferably a mol. ratio of methane to oxygen of about 1 : 1, or ethane to oxygen about 2 : 3, using super-atmospheric pressure and a temperature between 1150 DEG  and 1500 DEG  C.

Title: Improvements in or relating to methods of growing layers of silicon carbide on silicon carbide substrates
Inventor: BRANDER ROBERT WILLIAM
IPC: C23C16/32
Filed: 1963-04-29
Abstract: A layer of stoichiometric SiC is grown on a SiC substrate by exposing a mass of carbon, heated to at least 1800 DEG  C., to an atmosphere containing an inert carrier gas, and elemental Si or a volatile compound of Si, at a vapour pressure of 10-4-10-1 mm. Hg, to give an atmosphere containing Si and C, and exposing the substrate, heated to at least 1500 DEG  C., to this atmosphere.  Preferably a stream of Si containing gas is passed first over the carbon, e.g. graphite, and then over the substrate.  In one method, a graphite tube containing Si in a graphite boat and the substrate, is heated resistively so that the ends are at 500 DEG  C., the centre at 2,200 DEG  C., the Si at 1500 DEG  C. and the substrate at 2000 DEG  C.  The substrate is a monocrystalline plate, of hexagonal structure, mounted with its main faces (parallel to the 0001 crystal faces) vertical.  Argon is passed through at 1 l./min. and entrains Si vapour, which reacts with the graphite to form Si2C, SiC, and SiC2. In a second method, instead of using Si, the argon is passed through a Si compound e.g. SiHCl3 or SiCl4 before entering the tube.  The grown layer may be doped by adding to the molten Si or to the gas stream an impurity element or its volatile compound (e.g. halide), e.g. nitrogen (N-type) or BBr3 (P-type); or the impurity may be varied during growth to form PN junctions.

Title: Selective hydrogenation of í¸-3-ketosteroids
IPC: C07J3/00
Filed: 1953-06-18
Abstract: D 4,6-3-Keto-steroids are selectively hydrogenated with between about 2 and 2.2 moles of hydrogen per mol. of steroid in the presence of a palladium catalyst and a solvent, to yield the normal and allo isomers of the corresponding 3-keto steroid having saturated carbon atoms at positions 4, 5, 6 and 7 of the steroid nucleus.  Specified solvents are ethyl acetate, methyl alcohol, ethyl alcohol, isopropyl alcohol, dioxane and tetrahydrofuran, which may contain water up to 20 per cent by weight.  When the "normal" isomer is required the hydrogenation is carried out in the presence of a base, e.g. alkali metal hydroxides or carbonates, calcium hydroxide.  In examples: (1) 11a -hydroxy-6-dehydroprogesterone is hydrogenated in methanol using palladium-charcoal to yield a mixture of 11a -hydroxy - pregnane - 3 : 20 - dione and 11a -hydroxy - allopregnane - 3 : 20 - dione, which is resolved by chromatography.  Oxidation of these compounds with chromic acid yields the corresponding pregnane and allopregnane-3 : 11 : 20-triones; (2) 4 : 6 : 22-ergostatrien-3-one in methanol is hydrogenated in the presence of potassium hydroxide and a prereduced palladium catalyst to yield 22-coproergosten-3-one.  Further examples using the conditions of (1) describe the preparation of mixtures of: 22-coproergosten-3-one and 22 - alloergosten - 3 - one; 11a  - acetoxypregnane - 3 : 20 : dione and 11a  - acetoxyallopregnane-3 : 20-dione; coprostanone and cholestanone; etiocholane-3 : 17-dione and androstane-3 : 17-dione; etiocholane-17b -ol-3-one and androstane-17b -ol-3-one; pregnane-3 : 20 - dione and allopregnane - 3 : 20 - dione; pregnane - 17b  : 21 - diol - 3 : 11 : 20 - trione and allopregnane - 17a  : 21 - diol - 3 : 11 : 20-trione; the 21-acetates of the last-mentioned compounds; and pregnane-21-ol-3 : 20-dione and allopregnane-21-ol-3 : 20-dione.  Using the conditions of (2) the following compounds are prepared: 11a -hydroxypregnane-3 : 20-dione; 11a  - acetoxypregnane - 3 : 20 - dione; coprostanone; etiocholan-3 : 17-di-one; etiocholan-17b -ol-3-one; pregnane-3 : 20-dione; pregnane-17a  : 21 - diol - 3 : 11 : 20 - trione and its 21-acetate; pregnane - 21 - ol - 3 : 20 - dione.
